silicon nitride ceramic roller

Specification:

Silicon Nitride (Si3N4) Description:

Silicon nitride is a man made compound synthesized  through several different chemical reaction

methods. Parts are pressed and sintered by well developed methods to produce a ceramic.

The material color is dark gray to black and can be polished to a very smooth reflective surface.

High performance silicon nitride materials were developed for automotive engine wear-resistant

parts, such as valves and cam followers and proven effective. The very high quality bodies

developed for using in many severe mechanical, thermal and wear applications.

Key Silicon Nitride (Si3N4) Characteristics:

• Good thermal shock resistance
• Creep resistance
• Low density
• High fracture toughness
• High hardness and wear resistance 
• Electrical resistivity

• Rotating bearing balls and rollers

• Cutting tools

• Engine moving parts — valves, turbocharger rotors

• Engine wear parts — cam followers, tappet shims

• Turbine blades, vanes, buckets

• Metal tube forming rolls and dies

• Precision shafts and axles in high wear environments

• Weld positioners

1.What is information we provide when we inquiry?

You can send your complete drawing with technology requirements and the quantity you need.

If  you can, pls inform what’s application of your part?

We will try to recommend the most suitable material and quote for you asap.

2.Can you provide the free samples?

Yes,we can provide the free sample in stocked as customers with freight collected.

3.How long will it take for you to send me a quote?

This depends on the complexity of your requirements. For simple items such as

plates and rods, we can generally supply a quotation within 24 hours.

4.What's the delivery time?

For the standard products, like ceramic substrate and insulating rods, delivery time is

normally 7 working days. For hot pressed boron nitride and machinable glass ceramic,

it's about 10 working days. For customized products made of alumina, zirconia,

boron carbide and silicon nitride, total producing time is about 30-45 working days.

5.Do you have any certificate?

We have ISO 9001-2008;ISO9001-2008;OHSAS18001-1999 .
